Overview of display unit controls
The radar, video plotter, sounder and chart systems are operated with the
controls of the display unit (and the remote controller). Ten keys are labeled and
they provide the function shown on their labels. The five soft keys provide
various functions according to current operating mode. The [ENTER] knob
mainly functions to register selections on the menu and adjust the EBL, VRM
and gain. The trackball’s main function is to move the cursor across the screen.
When you correctly execute an operation, the unit generates a beep. Invalid
operation causes the unit to emit three beeps.
